Access Control List - Joomla! Forum - community, help and support

hi,

i'm having problems trying set access levels different groups can view different articles in 1 category list.

i have set following groups:
member (parent public)
a member (parent member)
b member (parent member)
c member (parent member)

i have set following access levels:
member (all members belong + supers users & administrators)
a member (a members belong + supers users & administrators)
b member (b members belong + supers users & administrators)
c member (c members belong + supers users & administrators)

i have category list menu item access set member (so members can see menu link once logged in).

i have created , set following article access levels:
article 1 (members)
article 2 (members)
article 3 (a members)
article 4 (b members)
article 5 (c members)

if log in member should able access articles 1 & 2. if log in member should able access articles 1,2 & 3, or b member articles 1, 2 & 4... etc. when log in 1 of these members none of articles visible (although link visible, it's visible registered users well, don't want!).

if log in super user or administrator can see articles, should.

can tell me i'm going wrong?

i repeat scenario on dev , works ! expected.
users "member" group can see list articles 1 , 2.
users "a member" group can see list articles 1,2 , 3
users "b member" group can see list articles 1,2 , 4
...

make sure category has public access rights.
